Namespace Change

This implements the discussed namespace change in the S3 buckets. It gets rid of the URL matching that was used to match against /edition/section/collectionid, in place of just ID.

This allows us to create different types of collections more easily that doesn't have anything to do with an edition or section.

Also provides an endpoint that will return the config.json file for a specific ID, although we are not yet using this.

Finally, facia changed to use new namespacing.
